POWER PUMPING DEVICE.

SPECIFICATION forming part of Letters Patent No. 788,679, dated May 2, 1905. Application filed June 15, 1904. Serial No. 212,604.

To all whom it may concern.-

Be it known that we, ALLEN PERCY SMrrIi and JAMES P. NnILsoN, citizens of the United States, residing at Montpelier, in the county 5 of Blackford, and in the State of Indiana, have invented certain new and useful Improvements in Power Pumping Devices, of which the followingis a full, clear, and explicit description, such as will enable others skilled in the art to I which the invention relates to make and use the same.

Our present invention relates to a device operative from a single source of power, as an engine, whereby a plural number of operating- 1 arms may radiate therefrom, being geared for horizontal reciprocation and each adapted to operate a pump in connection with a well.

This invention is intended particularly to be used in connection with the pumping of oilwells, whereby a number of wells may be pumped from a single source of power, our construction being the medium receiving the single or direct action of the power applied and distributing the power to a number of 5 points for actuating other devices.

Our object is the production of a power pumping device by the interposition of which a number of oil-wells or the like may be pumped from a single source of power, and

3 that without regard to the distance of the wells with reference to the source of power, and to provide specific parts and devices in order to accomplish certain definite and advantageous results.

Another and more specific object is to provide a power pumping device in which we employ a horizontally-disposed revoluble pullwheel, whereby the operating-arms and the actuating pitman are coupled tangentially 4 thereto in a new and positive manner in order to provide the greatest degree of simplicity and mechanical efiicieney.

Other objects and advantages of our invention will be made manifest from the following specification, and the operation and construction will appear from the accompanying drawings, forming a part thereof.

This invention relates to power pumping devices, and our preferred construction is illustrated in the accompanying drawings, in 5 which- Figure 1 is a top plan view of our pullwheel, the actuating-pitman, and a number of operating-arms in connection therewith. Fig.

2 is a central cross vertical section of our pullwheel, taken on the line X X of Fig. 1, also showing in section the supporting and securing means for the pull-wheel. Fig. 3 is an enlarged elevation of a portion of the periphcry of the pull-wheel and of the pitman in eonnection therewith. Fig. 4': is an enlarged top view of the pitman connection shown in Fig.

3 and at vertical right angles therewith. Fig.

5 is an enlarged rear view of said pitman connection as shown in connection with a portion 5 of the periphery of the pull-wheel in section. Fig. 6 is an enlarged detail view showing a plan of the inner end of one of the operatingarms. Fig. 7 is a detail sectional view taken vertically and centrally through a portion of 7 one of the brasses and one of the shackle-bolts. Fig. 8 is a detail elevation of one of the coupling-pins, and Fig. 9 is a detail plan of the coupling-pin shown in Fig. 8.

Similar reference characters refer to and denote similar parts throughout the several views of the drawings.

In Figs. 1 and 2 of the drawings is shown a horizontally-disposed pull-wheel consisting of a rim 1, provided with an upper and a lower peripheral escalloped flange 2 and 3, respectively. The numeral 4 denotes the hub of our pull-wheel, and the numeral 5 denotes the four (or more) spokes radiating from the hub 4; to the rim 1. The said parts 1, 2, 3, 4:, 3 5 and 5 we prefer to form integral with each other, as is indicated in the drawings. The hub 4 is provided with a central downwardlyexpanding aperture to receive the spindle. The lower end of the hub is provided with a 9 flange t extending therearound, and in the lower level face of said flange of the hub is formed a circular half-round channel A", in

which may travel a plurality of balls 7 and 7 The letter A denotes the pony-sill of the framework or the base on which our pull-wheel is mounted, said base being of any preferred form of construction sufflcient to withstand the strains placed upon it.

The numeral 8 denotes the base-block of our construction, to be secured on top of the ponysill A by a plurality of bolts 9 and 9, which pass through apertures therefor formed in the flange of the base-block, as shown in Fig. 2.

Extending up centrally from the block 8 is the spindle 6, above referred to, and which is adapted to fit the said central aperture of the hub, as shown. The block 8 and the spindle 6 are formed integral with each other, as indicated in Fig. 2.

Formed in the upper face of the block 8, extending equidistant around the spindle 6 and oppositely disposed to the channel 4:", is the half-round channel 8, also adapted to receive a plurality of the balls, as 7 and 7. The size of said balls is such as to slightly suspend the hub resting thereon, as shown in Fig. 2.

Extending centrally and in an axial direction through the spindle 6, the block 8, and the pony-sill Ais an aperture to receive the studbolt 10, placed loosely therein to bind said parts together, as shown.

Around the upper portion of the bolt 10 is a cap-Washer 11 of a diameter suflicient to extend over the upper level face of the hub 4, and around the lower portion of the bolt 10 is a foot-washer 12 to contact with the under side of the pony-sill. The upper and lower ends of the bolt 10 are threaded to receive the nuts 13 and 14, respectively. It will now be seen that the pull-wheel may be mounted for horizontal reciprocation or revolution, as shown in Fig. 2. A tangent of one portion of the flanges 2 and 3 is cut away at one portion, as at b in Figs. 1 and 3, for the purpose presently appearing. Through the flanges 2 and 3 and central of the said flanges and also central of each of the escallops are formed the circular apertures 15,with a pair of oppositelydisposed wing-cavities extending out from each of said apertures in the upper face of the flange 2, extending down into but not entirely through the thickness of said flange, as is indicated.

The numeral 17 denotes a coupling-pin having a key 18 extending horizontally through its upper portion and adapted to extend down partially into the cavities 16, substantially as indicated, thus allowing the pin 17 to be inserted in the aperture and extend down through and below the flange 3, but supported and prevented from turning by the said key 18. The lower end portion of the pin 17 is threaded to receive the nut 19, as in Fig. 2.

The numerals 20, 20, and 20 denote the operating-arms, any number of which may be employed and which may extend out horizontally in any direction, the inner end of each being provided with a round head 21, having flat upper and lower faces of a thickness to neatly fit between the flanges 2 and 3, and with a central aperture formed therethrough to receive one of the pins 17, and said arms may be extended any desired distance to connect with pumping-jacks or the like for which the power is required.

The numeral 22 denotes the single actuating pitman. (Shown in Fig. 1 and shown on a larger scale in Figs. 3 and 4.) This pitman is connected to the pull-wheel by a universaljoint coupling of novel construction, as shown in Figs. 3, i, and 5. At one end of the said segmental line b is an aperture 23, which passes through the flange 2, and the aperture 24;, 0pposite thereto, through the flange 3, as shown in Figs. 1 and 5. The apertures 23 and 24: are located central of the flanges 2 and 3 and central of the escallop located at the outer terminal of the segmental line 6 and may under certain conditions be larger than the apertures 15. The aperture 23 has a pair of oppositelydisposed wing-cavities 25 extending therefrom, formed in the upper face of the flange 2. The lower part of the aperture 2 1 we prefer t0 form of less diameter than is its upper portion, as is indicated in Fig. 5, to form a seat, as shown.

The numeral 26 denotes the pitman couplingpin, having akey 27 extending horizontally through its upper portion andbeing adapted to lit in said cavities 25, as indicated in Figs. 3 and 5, to prevent the pin 26 from turning. The pin 26 has an offset in its lower portion, adapting it to fit said offset in the aperture 2 as shown in Fig. 5, and the reduced lower end of said pin 26 is threaded to receive thereon the nut 28, by which the pin 26 is secured, as shown.

The letter B denotes the cylindrical vertical body, having cylindrical oppositely-disposed branches 0 and 0" extending out perpendicularly therefrom, as shown. Extending centrally in an axial direction through the member B is a bore of a size to receive the pin 26, on which the member B may revolve. Around the peripheries of the branches 0 and C, near their ends, are formed grooves to receive the inner edges of the brasses 29 30 and 31 32, respectively, the brasses 29. and 31 having square outer edges, while the brasses 30 and 32 are crescent shape. The peripheries of the brasses 30 and 32 and the upper and lower edges of the brasses 29 and 31 are provided with substantially half-round channels therein to form beds for the respective shackle-bolts 33 and 34. On the end of the pitman 22 is permanently secured an oblong plate 35, having four holes therethrough near its corners, so positioned as to allow the threaded ends of the bolts 33 and 34 to pass therethrough and to receive against its outer face the nuts 36, which are threaded on the ends of said bolts, and with the square edges of the brasses 29 and 31 adapted to abut against its inner face, as indicated in the drawings.

From the above-described construction it is apparent that by inserting the pin 26 in the opening 23, passing it through the bore of the member B, and then through the aperture 24:,

then tightening the nut 28, the key 27 will be seated in its cavity 25. By placing the brasses 29 30 and 31 32 around the respective branches 0 and 'G and by disposing the bolts 33 and 34 around the respective brasses, as shown, then entering the ends of the bolts through the holes in the plate 35, then by tightening the bolts 36, the various parts will be held in contact and the pitman 22 will be provided with a universal connection with the pulhwheel.

When assembled as set forth, the outer end of the pitman 22 may be connected with the piston of a reciprocatory engine in the usual manner, allowing the pitman to actuate the pull-wheel back and forth approximately oneeighth of a revolution, a portion of the flanges of the pull-wheel being cut away on the line 7) to allow the pitman 22 to have a vertical as well as a horizontal motion.

When assembled as above set forth, the desired number of the operating-arms may be connected to the pull-wheel in the manner stated to extend out to the desired working points. 7

In the consideration of our present invention as a whole the manner of coupling the pitman to the pull-wheel, the manner of con necting the operating-arms to the pull-wheel, the manner of mounting the pull-wheel on ball-bearings, and the manner of securing the pull-wheel in operative position may be regarded as constituting the main or important features of the invention and the detail parts and devices as auxiliary thereto, ,the combined mechanism and construction being nicely balanced and proportioned for the accomplishment of a definite resultthat is, the trans mission of power.

From the above description, taken in connection with the accompanying drawings, it Will be seen that we have produced an improved power pumping device embodying the objects elsewhere referrcd to in this specification, and while we have illustrated and described the best means now known to us for carrying out our invention we desire it to be understood that We do not restrict ourselves to the exact details of construction shown and described, but hold that any changes or variations therein as would suggest themselves to the ordinary mechanic would clearly fall within the limits and scope of our invention.

Having now fully shown and described our invention and its intended application and operation,what we claim, and desire to secure by Letters Patent of the United States, is

In a power pumping device, the combination of a pull-wheel having a pair of peripheral flanges cut away as at 6 in one part of the periphery, with a power-transmitting arm or arms pivoted at one end between said flanges and an actuating-pitman pivoted by universal joint between said flanges in proximity to said cut-away part 6, whereby the said wheel may be driven from a point out of its plane, avoiding all obstructive contact of said pitman with eitherof said flanges substantially as set forth.

In testimony whereof we have hereunto signed our names to this specification in the presence of two subscribing witnesses.
